The shitty German translations are a big turn off for me, to be honest. Looks like a bot translated phishing mail...
It might be tolerable for a free as in beer service, but if anybody wanted me to pay for it, do the translation properly (e.g. hire somebody for a few bucks), or focus on languages you mastered first.
I am more likely to pay for a "proper" English-language service than a crappy "German"-language one, but that does not necessarily translate well to other Germans.
In Czech version they call their "Premium" plan button as "Insurance".
This is good point for monetising side projects: if you are going to create international version, spent 20 USD on people who actually speak that language or keep it in English.
First things first: Probably some copyright concerns you need to look at. The second you start charging to download the MP4 for them, you will be much more legally liable.
Now that that is out of the way, the only way to make something like this more legit looking and be able to monetize is to wrap it into a product.
The domain name is actually a very big asset. An almost English-sounding 4 letter word is very rare. Hold that as long as you can! If you have to go without food for a month to renew it, do that!
To wrap this into a product, you will want to add additional features.
1) Sign up for an account
2) Create a project
3) Import a video from youtube or your computer (also a checkbox saying they are allowed to)
4) Edit the video, drag other imported videos around, etc.
5) Download or Send to YouTube (with a watermark unless you are premium)
The clicking and dragging can be pretty simplistic, just use the thumbnail and have a start and end time for clipping the video shorter.
Its a lot of work, and it has been done before, but if you make it simple to use and cheap enough, you could probably make $15/mo or $150/year.
Just be sure to find a good admin theme from wrapbootstrap.com or themeforest.net
In terms of legal, check tivo.com for a publicly traded example, transcoding is legal due to the betamax ruling. The site is already pretty large (5+ million visitors a month), but I do like the video mashup option. Thank you
No problem, and that is a lot of visits, and that domain is awesome! As for legal things, I'm not a lawyer, so I don't know the law, but if its legal, then go for it, if it isn't, still go for it, then ask for forgiveness ;).
The landing page took quite some time to load for me and I was wondering why it loads so much JavaScript. I think Angular is only needed for the actual application, not the static content pages, isn't it? Would load faster that way.
Btw: Your German translation is so bad, I would rather keep it English. "Premium" is translated as the German word for "bonus" or "bounty", while "Premium" itself is a perfectly fine German word. This probably hurts the conversion rate more than it helps.
Maybe use a looped embedded video instead of GIF? You can get much higher quality with a smaller file size. If you have a lot of users on IE8, you could fallback to GIF.
